LIFTING DEVICE.

Specification of Letters Patent.

Patented oct. 30,1906.

Application filed March 7, 1906. Serial No. 304,795-

To a/ZZ :whom t may concern:

Be it known that I, JOHN HARTOGH, a citizen of the United States, residing in Douglas township, in the county of Mitchell and State of Iowa, have invented certain new and useful Improvements in Lifting Devices; and I do hereby declare the following to be a full, clear,` and exact description of the invention, such as will enable .others skilled in the art to which it appertains to make and use the same.

My invention relates to lifting devices particularly adapted for raising hay-racks and Wagon-bodies from the running-gear of vehicles and for liftin the body portions of sleds.

` The object of t e invention is to provide a simple and inexpensive device of this charf acter which is formed of but few parts and which can'be used to easily lift a rack or body and su ort it. i

A stiffurther object is to provide a lifting device which is adjustable for use in connection with vehicles 'of different sizes.

i The invention consists of side rails which are inclined, and hoisting-levers are pivoted to which they may be swung. These levers are connected by a detachable bar adapted laced under the rack or wagon-bed after t e same has been drawn into contact with the rails, andby pulling forward on the levers the rack or body will be drawn upward on the rails and sup orted by them and the levers will be so he d until it is desired to lower it. V

The invention also consists in further novel construction and combination of arts hereinafter more fully described and c aimed.

In the accompanying drawings I have shown the referred formv of my invention.

In said rawings, Figure 1 is a side elevation of my improved lifting device and show-'- ing a'wagon'in position therein, the body of the wagon being disclosed by dotted lines in raised osition. Fig. 2 is a plan view of the Fig. 3 is an'enlarged view, partly in section and partly in' eleva'- tion, o the locking device used in connection with the draft a pliance of the lifting device. Fig. 4 is a top pian view of my lifting device.. Fig."5 is an elevation of the lifting-`levers re# moved from the device, and Fig. is'an 1en'- larged detail sectional view of one Tof'th'elifting-levers and adjacent parts.

Referring to the figures by numerals of reference, 1 1 are parallel rails spaced'apart a distance slightly greater than the width of a vehicle and rack thereon, and these Irails are supported at one end by long standards 2 and at their other ends by short standards 3, said rails being pivoted to the standards 3 and f extending slightly beyond the same, while the opposite ends of said rails are adjustably secured to the standards 2. Pivoted to leach of these standards 3 at a point below the ground is a lever 5, having a slot 6 in its upper end. Another slot 7 is formed in each of these levers 5 at a point below the upper end thereof, and a toothed arm 8 is pivoted to each standard 3 and normally rests by gravity on a lug 9, extending from the levers 5. The slots 6 are adapted to receive the ends of a cross-beam 10 when the lifting de# vice is used-in connection with a vehicle havl` ing a high rack or wagon-bed but where the device is used in connection with a vehicle having its bed near the ground this beam 10 is adapted to be inserted into the slot 7. Blocks 11 vare secured to the beam 10 adjacent each end thereof, vsaid blocks abutting against the inner faces of the levers 5, whereby said levers are spaced auniform distance apart and prevented from moving inwardly toward each other. The levers 5are held from spreading apart by means ofsup lementary rails 12, said rails being secure at one end to the standards 3 and at their opposite ends to standards 13.

The movement of the levers 5 in one direction is limited by means of a rod 14, secured to or formed integral at each end with the toothed arm 8 ,whereby a way will be formed between the teeth on said arm and the rod in which the lug -9 travels, so that when the lug 9 has reached the outer end of the arm 8 the 'lug willcontact with the vertical portion of the'rod 14 and prevent said levers from being moved farther downward. Notches are cut `tion by strips 16, said strips being secured at one end to the standards and at their opposite ends to the free end of the bracing memlbers `15, said strips and braces forming seats for the ylower ends of the levers 5. One of the-levers 5 isprovided with a releasing device'comprising a rod 19, having a hooked end 20'and a head l21 at its opposite end.

VThe rod 19 passes entirely through'the lever 5, while the hooked end thereof passes partly roov IIO

through, said hooked end being designed to I engage a ring 22, secured to one end ot' a rope or cable 23, which extends around the pulley 2&1, said pulley being carried by a doubletree 25. The other end of the cable 23 is fastened to the other lever 5.

As best shown in Fig. 8 of the drawings, the hooked end 2O of the rod 19 passes centrally through the opening 26 in the lever 5, so that when the ring 22 is inserted in said opening and the rod 19 moved longitudinally through the lever 5 the hooked end 20 will pass through said ring and hold the same until released.

In using the apparatus herein described the vehicle is placed in position for the rack or bed thereon to be engaged and operated, and when so placed the levers 5 are swung downward as far as they will go and the cross-bar 1() placed therein, said bar being disposed beneath the rack or bed, as shown in Fig. 1 of the drawings. A pole 27 is then inserted beneath the front end of the rack or bed, said ,pole being of suflicient length to engage the side rails 1 and is held in position thereunder by means of blocks or the like (not shown) on the under side of the rack. The ring 22, secured to the cable 23, is then placed into engagement with the lever 5 and the doubletree 25 secured to the pulley 24, and when a forward pull is .made upon said doubletree the rack 28 will be moved upwardly on the rails 1 and the rear end thereof elevated by the levers 5 until the same has assumed the position shown in dotted lines in Fig. 1. When the levers 5 have reached a vertical position, the head 21 of the rod 19 is directed into -contact with the standard 3 and the bolt 19 forced longitudinally through said lever, thereby disengaging the hooked end 20 from the ring 22, and thereby stopping the upward movement of the rack 2S. As the levers 5 swingl upward the arms 8 will slip over the lugs 9 and retain said levers in their adjusted position until such time as it is desired to lower them again.

To more securely hold the rack 28 in its elevated position, l have provided clevises 29, said clevises being pivotally secured to eyebolts 29 or the like, which take into the outer faces oi the rails 1 said clevises being so located that when they are swung up they will take over the projecting ends of the pole 27, properly located between the rack and rails. When the pole is removed from the clevises, they will normally swing downwardly and out of the road when the rack is being slipped npwardly on the rails 1. When it is desired to replace the rack or bed upon the vehicle, the pole 27 is removed from under the iront end of said rack and that end of the rack lowered onto the front bolster of the vehicle, and, if desired, a rope can then be secured to the front end of the rack and wrapped one or more times around the pole 27, said pole having been deposited in brackets 30 on the standards 2, the outer faces of said standards serving as bearings for the pole. The arms S are then released from the lugs 9 and the vehicle shoved rearwardly until the levers 5 have been lowered a suiiicient distance to rest the rack 2S on the rear bolster oi the vehicle. The rope secured to the iront end of the rack and around the pole 27 regulates the descent of the rack. By providing the rails 1 with a series of holes 31 and the standards 2 nu'th a series of holes 32 the said rails 1 may be raised or lowered and adjusted to suit the height of the vehicle. By having the pivoted end of the rails 1 projecting slightly beyond the standards 3 it will be seen that when the levers 5 are elevated they will be disposed between said projecting ends and the supplementary rails 12, whereby said levers will be held against lateral movement.
